FRANK C. BROKISH, OF DODGEVILLE, WISCONSIN.

PUlVlP-TI-IAWING MEANS.

Application filed April 15, 1918.

To all whom it may concern:

Be it known that I, FRANK C. BROKISH, a citizen of the United States, residing at Dodgeville, in the county of Iowa, State of WVisconsin, have invented certain new and useful Improvements in Pump-Thawing Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to pumps, more particularly to a stock or pump casing having a discharge spout at its upper portion and having an annular partition adjacent and below the discharge spout, into which is threaded the upper end of the pump barrel, the top of the pump casing being closed by a removable cap in which the pump rod is slidably mounted.

It is the object of the present invention to provide a means for thawing out the pump barrel by the application of hot water thereto, when the water. is frozen to prevent operation of the pump.

To this end the invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and particularly pointed ou in the appended claims.

In the accompanying drawings:

Figure 1 is an elevation of a pump casing embodying the present invention.

Fig. 2 is a vertical sectional view through the center thereof.

Fig. 3 is a transverse sectional view on the line 38 of Fig. 1.

Referring now more particularly to the accompanying drawings, 5 designates a tubular pump casing, having its upper end closed by a removable cap 6 and having its lower end open and flared to a base 7 to seat on the well cover. At the upper portion of the pump casing, a discharge spout 8 extends laterally therefrom, and below and adjacent this spout the casing is provided with an internal partition 9 into which is threaded and through which opens the upper end of the pump barrel 10 which leads down through the base into the well. The pump rod 11 extends loosely through the barrel and is guided in the cap 6 and worked by its handle in the usual manner. That portion of the casing above the parti- Specification of Letters Patent.

tion 9 thus forms a water head, and between the pump barrel 10 and the lower portion of the casing there exists an annular space.

Heretofore, the method of thawing the pump rod 10 has been to remove the cap 6 and pour hot water into the water head. My invention resides in the provision of means affording access to the annular space between the casing 5 and the barrel 10 whereby hot water may be poured directly against the exterior of the barrel 10, to flow downwardly along the same and quickly and effectively thaw the accumulation of icetherein. To accomplish this, the pump casing is provided immediately below the partition 9 with an opening 12 which is normally covered by a plate 13 carried by a pivoted suspendin arm 14 whereby a plate 13 curved to con orm with the periphery of the casing as'seen in Fig. 3. This plate is supported by an arm'l4' pivoted to the casing, and provision is made for permitting the plate to be swung aside as seen in dotted lines in Fig. 1, as by having the arm resilient or making its pivot loose. When hot water is poured in through the opening it strikes the barrel just below the partition, I

and the ice plug therein is thawed by the heat of the barrel up to the point where water poured into the head would reach it, and down as far as the plug extends. Therefore the pump is soon restored to service, and then the plate 13 is swung back to. place.

What is claimed is:

In a pump, the combination with the barrel, and the piston rod rising through it to the operating mechanism; of a cylindrical casing appreciably larger than the barrel and having an internal partition through which the upper end of such barrel is screwed, the casing having a spout, and an opening in its wall immediately below the partition, a plate curved to fit against the casing and of a size to close over its opening, and an arm rising from the plate and pivoted to said casing so as to allow the plate to bemoved to expose said opening.

In testimony whereof I afiix my signature in the presence of two witnesses.

FRANK C. BROKISH.
